    • An adaptive gate drive for an inverter includes control circuitry having a Field Programmable Gate Array (FPGA) and includes power circuitry having a plurality of FETs for operating a switching device, such as a Trench Gate Insulated Gate Bipolar Transistor (IGBT device). The control circuitry provides switching signals for operating the switching device. In addition, the control circuitry receives signals of output current of the IGBT device, temperature of the IGBT device, and DC link voltage. The FPGA has a plurality of operating points stored therein. Each operating point has corresponding parameters for a control signal that is used to control the turn-on or turn-off behavior of the IGBT device. During operation, the control circuitry compares the measured current, voltage and temperature operating points stored in the FPGA and sends the corresponding parameters to the gate drive circuit. The gate drive modifies the signal on the gate of the IGBT accordingly and thereby optimizes the turn-on and/or turn-off behavior of the device based on actual operating conditions.
    • 用于逆变器的自适应栅极驱动器包括具有现场可编程门阵列(FPGA)的控制电路,并且包括具有用于操作诸如沟槽栅绝缘栅双极晶体管(IGBT器件)的开关器件的多个FET的电源电路。 控制电路提供用于操作开关装置的开关信号。 此外,控制电路接收IGBT器件的输出电流信号,IGBT器件的温度和直流母线电压。 FPGA中存储有多个工作点。 每个工作点具有用于控制IGBT器件的导通或关断特性的控制信号的相应参数。 在操作期间,控制电路比较存储在FPGA中的测量电流,电压和温度工作点,并将相应的参数发送到栅极驱动电路。 栅极驱动器相应地修改IGBT的栅极上的信号,从而基于实际操作条件优化器件的导通和/或关断特性。
